CGPA to GPA Converter
Convert a CGPA on a 10-point or any other scale to the US 4.0 scale, or turn a CGPA into a percentage with your board's or university's formula.
How the conversion works
To put a CGPA on the US 4.0 scale, divide it by the top of your scale and multiply by 4. A CGPA of 8.2 out of 10 becomes 8.2 ÷ 10 × 4 = 3.28. The same works for any scale: 4.1 out of 5 is also 3.28, and 85% is 85 ÷ 100 × 4 = 3.40.
For a percentage, there's no single formula: it depends on who gave you the CGPA. CBSE's Class 10 CGPA results gave an indicative percentage of 9.5 × CGPA, so 8.2 becomes 77.9%. Universities set their own rules, such as CGPA × 10 or (CGPA − 0.75) × 10, and some have changed them from one set of regulations to the next.
| CGPA (of 10) | 4.0 GPA | % (× 9.5) | % (× 10) |
|---|---|---|---|
| 10 | 4.00 | 95% | 100% |
| 9.5 | 3.80 | 90.25% | 95% |
| 9 | 3.60 | 85.5% | 90% |
| 8.5 | 3.40 | 80.75% | 85% |
| 8 | 3.20 | 76% | 80% |
| 7.5 | 3.00 | 71.25% | 75% |
| 7 | 2.80 | 66.5% | 70% |
| 6.5 | 2.60 | 61.75% | 65% |
| 6 | 2.40 | 57% | 60% |
| 5 | 2.00 | 47.5% | 50% |
These are straight conversions of your overall CGPA. They're useful for a quick comparison, but they aren't how an admissions office or an evaluator works out an official GPA.
Which number should you put on an application?
- Follow the form's instructions. Many applications ask for your GPA together with its scale, and some ask international applicants not to convert their grades. If a form asks for both, enter your CGPA as it is, for example 8.2 out of 10.
- If a university asks for a credential evaluation, it uses the evaluator's GPA. Evaluators such as WES convert each of your course grades to a US grade and then average them, which is a different method from scaling your overall CGPA, so the two numbers can differ. WES has a free iGPA Calculator that estimates your GPA on the 4.0 scale before you apply.
- If you need an official percentage, ask your university's examination section, which may issue a conversion certificate.
Grades in a single US class work differently again: an 85% there is usually a B. To see what a score means in a US class, use the test grade calculator.
